【摘要】 在硝酸铈-草酸-尿素体系中采用水热法成功合成出氧化铈纳米球,得到了均匀单分散且直径在50 nm左右的氧化铈纳米球。通过XRD、FE-SEM、BET等表征手段进行了综合分析,发现纳米球具有较大比表面积57 m~2/g。更多还原

【Abstract】 In this work,ceria nanospheres were successfully prepared in the Ce（NO₃）₃-C₂H₂O₄-CO（NH₂）₂ system by using hydrothermal method.These nanospheres had diameter about 50 ran,which took on uniform and monodisperse sphere shape. Comprehensive analysis was obtained by means of XRD, FE-SEM,BET and etc.Results showed these nanospheres possessed larger specific surface area（about 57 m²/g）.更多还原
